Which of the following correctly depicts the attainment of equilibrium for the reaction: `N_2(g)+3H_2(g)hArr2NH_3(g)` beginning with stoichiometric amounts of `N_2(g)` and `H_2(g)` and no `NH_3(g)`.A. B. C. D. |

Answer» Correct Answer - B In the beginning (when time is zero), the concentrations of `N_2` and `H_2` are maximum and the concentration of `NH_3` is zero (because no `NH_3` is present in the container). When `N_2` and `H_2` react, their concentrations decrease with time while the concentration of `NH_3` increase due to its formation. When equilibrium is attained, there is no net reaction. Thus, the concentrations of `N_2`, `H_2`, and `NH_3` become constant. |
